test could mean ninja check or llvm-test-suite, perhaps change this to testsuite_use_lnt to match the other parameter? Then it's more clear what it changes.

What logs do we get from the cmake only test suite build? Is it just like a normal ninja check-all, stdio with the output, ending with a table of results?

As most buildbots run these test for validation I have kept the log to mimic logs output generated by llvm-project's ninja check-all

If we run ninja check it will actually run llvm-lit -sv . which generates logs like we get in llvm-project ninja check-all.

For detailed logs We should run llvm-lit . with sv to get logs like following:

That part is fine, 99% of the time I'm looking at the "stdio" file anyway.

Is buildbot still able to parse the failures correctly and show the various failure types in the UI? (I forget if it parses the stdio or the json results file)
